COMBINATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 597,712, dated January 25, 1898. Applicatlonfiled October 12,1896- $erial No. 608,615. (No model.)

To all whom it may concern:

Be it known that 1,3 OHNTURNER ELnnIncE, a citizen of the United States, residing at Murfreesborough, in the county of Hertford and State of North Carolina, have invented a new and useful Combination Door-Lock, of which the following is a specification. I

This invention relates to combination doorlocks, and has for its object to provide a safe, reliable, and durable lock which is particularly designed to be applied to the outside of box-cars, storehouses, barns, 820., and be op erated without the aid of a key, the said lock being constructed so as to be water and rust proof, not liable to freeze, and being capable of being easily taken apart for the purpose of cleaning and oiling the several parts thereof and changing the combination whenever required or deemed advisable. The bolt and look-case are formed in one piece, the lock mechanism being carried by the bolt, and the bolt being made removable, so that it, together with the lock mechanism, can be easily detached for cleaning or" repairs.

The invention consists in an improved combination door-lock embodying certain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective View showing a portion of a car and car-door with the improved lock applied thereto. Fig. '2 is a longitudinal section through the lock. Fig. 3 is a cross-section through the same. Fig. 4' is a detail perspective View of the combined bolt and lock-case. Fig.5 is a similar view of the inclosing case. Fig. 6 is a detail perspective view of one of the tumblers. Fig. 7 is a similar view of another tumbler of slightly-different forum.

Similar numerals of reference designate corresponding parts in the several figures of the drawings.

1 designates a portion of a car-body, and 2 a portion of a sliding car-door. The car-door is provided with the usual hasp 3, and a staple i is driven into the car-body, preferably into the door-post 5,in the ordinary manner, said staple being adapted to receive the hasp.

6 designates a stationary rod or bar, which is shown as applied to the door-post above the staple. This. rod or bar is bent at its lower end'and extended through the door-post and secured by one or more nuts '7 or in any other convenient manner, while the main body of the rod or bar extends vertically and in parallel relation to the door-post, being spaced a slight distance therefrom and provided at its inner side with nibs orprojections S at spaced intervals.

' 9 designates the bolt, which is adapted to en ter the staple 4i and prevent the escape of the haspf This bolt has formed integrally with it and at its rear end a lock-case 10, which is substantially se micylindrical in cross-section. The lock-case is of oblong form and is provided at regular intervals with cross webs or partitions 11, forming integral parts of the lock-case and connected and braced at the inner side of the case by means of a longitudinal integral bar 12. These webs or partitions, as well as the end walls of the lock-case, are provided with corresponding and longitu'dinally-alined circular openings 13 for the reception of the rod or bar 6, and each and all of these openings are provided with longitudinall y-alinin g notches 14, forming radial extensions of the openings and adapted to permit'the passage of the nibs or projections 8 on the rod or bar 6 when the bolt and lock caseare slid longitudinally of said rod or bar. In the intervening spaces between the webs or'partitions 11 and the end walls of the lock case are arranged rotary tumblers 15 in the form of disks or cylinders, as shown in Figs. 6 and 7. These tumblers are insertible and removable through the front wall of the lockcase, and each tumbler is provided with a cen tral circular opening 16 and one or more notches 17, the said openings and notches corresponding to those in the webs or partitions 11, above described, and adapted to aline therewith. Each of the tumblers is also provided at one side with an annular rabbet 18, which will admit of the tumbler being rotated while the nib or projection 8 of that particular tumbler rests in such rabbet. In order to slide the bolt, the tumblers must be r0- tated until the notches 1'7 of the tumblers are brought into alinement with the notches 14 in the lock-case, whereupon the combined bolt and lock-case may be slid longitudinally of the rod 6 and withdrawn from the staple i.

The tumblers are brought into the proper position for unlocking the bolt with the aid of the combination of the lock. The end of the lock-case is closed by an imperforate wall 20 for excluding rain, ice, snow, (to.

21 designates an inclosing case or cover which is of substantially semicylindrical form and slidingly mounted on the combined bolt and lock-case. This case or cover is provided near its opposite edges with longitudinal slots 22, through which extend headed studs 23 on the lock-case. This construction permits the cover to be slid on the lock-case so as to expose the tumblers to view or entirely conceal the same. The inner end of the cover 21 is also provided with open slots or notches 24:, which engage headed studs 25 on the lockcase to prevent the cover from rocking and rattling while the car is in motion. The upper end of the cover 21 is closed by an inclined end wall 26, which serves to shed the water, cinders, and dirt falling thereon and prevents the same from entering the operative parts of the lock.

While the improved lock has been shown and described as applied to a sliding car-door, it will be apparent that the same may be used in connection with the doors of storehouses, barns, &c., either with or without the hasp and staple, and that it may be secured to the door or door-post either in a vertical or horizontal position. It will be seen that the lock mechanism is carried byand contained Within the bolt or the lock-case, which forms a part thereof, so that when the bolt is detached the lock mechanism is at the same time removed therewith, thus allowing the several parts of the lock to be taken apart, cleaned, or repaired, and again assembled, either in the same or a different order, for changing the combination.

It will also be understood that the lock is susceptible of changes in the form, proportion, and minor details of construction which may accordingly be resorted to Without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, What is claimed as new is- 1. In a look, a bolt adapted to be removably inserted in an opening, a lock-case rigidly attached to the bolt and movable therewith, said case being adapted to fit over a fixed rod or bar, and mechanism carried by thecase to lock it to the bar, substantially as described.
